      1. unzip EAP
      2. ./bin/standalone.sh
      3. /subsystem=undertow/server=default-server/http-listener=default:write-attribute(name=enabled, value=false)
      4. reload
      5. look in the server log for warning

    Description

      When I set http-listener as not enabled in Undertow subsystem and perform reload operation, during the server shutdown I can see following NPE exception/warning in the server log:

      19:26:59,020 WARN  [org.jboss.msc.service.fail] (MSC service thread 1-4) MSC000004: Failure during stop of service jboss.remoting.remoting-http-upgrade-service.http-remoting-connector: java.lang.NullPointerException
	at org.jboss.as.remoting.RemotingHttpUpgradeService.stop(RemotingHttpUpgradeService.java:154)
	at org.jboss.msc.service.ServiceControllerImpl$StopTask.stopService(ServiceControllerImpl.java:2071)

	at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617)
	at java.lang.Thread.run(Thread.java:745)

      Such exception is not present when I keep http-listener enabled before reload operation.

          • Minor - To be worked after urgent, high, and medium priorities are resolved. This term is chosen when the severity of the issue is low, or the complexity or effort to correct it may be higher, relatively speaking. For low priority issues, known workarounds exist or are not needed due to the trivial effort needed to address the issue.

          Bug - A problem that impairs or prevents the functions of the product. JBEAP-6460 Undertow subsystem is misleading about listener capabilities

          • Major - To be worked after higher priority work items are addressed. When the severity is high and the effort to change it is low to moderate, this term is chosen. Issues in this category likely have an existing workaround but implementation or execution may be non-trivial.
